After testing the R0DE NT-USB with Camtasia on three different computers, installing different video cards (I almost bought another one because I was told there might be an issue with NVidia cards), I finally figured out what was causing all the problems with the NT-USB with Camtasia.

Problem SOLVED: In one test on a different computer I didn’t want to reroute the cable again so I pulled an old one out of my box of spare computer parts. The R0DE mic and Camtasia performed perfectly.

About 3 in the morning I started thinking... could it be the CABLE??? That morning I connected the spare cable I had used in the testing to the original location.... and all the problems went away. The repeated “beboop, bebeep, beboop” USB connection sounds, the issue with Camtasia, the volume indicator that showed steady sound when there was none... all gone. It works PERFECTLY. No need to return the Rode, no need to replace as defective, no need for a new video card, no need for new video drivers. Just replace the poorly insulted R0DE USB cable. Hours of frustration and disappointment... for THAT!!! The cable is also much too long, so I also recommend NOT coiling it up to get rid of the extra length. That’s where the “click click” in the headphones likely came from: simple cross-talk between signal out and signal in.

OMG Thank you so much for sharing this. I was getting so frustrated with my sound card thinking it is the problem, My head is spinning because I was overthinking and didn't know what to do since i got stuck with this mic that I bought to record video tutorials with it using Camtasia. my question to you is what typoe and brand of cable you ended up replacing it with? thank you again

I didn't buy a USB cable, I simply went to my "junk box" and pulled one out. I decided that the issue had to be shielding so I picked one that had a clear outer covering that showed a thick braided shield inside. It turns out I have a couple like that. I don't know but I think they may have come with printers some time back. I am convinced that the key a thick cable that is short (4 feet or less) with braided (not spiral) shielding. Other than in a recording studio, perhaps, the long, thin cable that comes with this mike is just asking for trouble.
